The process of accumulation of non-biodegradable substances in increasing concentrations at successive trophic levels is known as:

A.RAMA NAGESWARARAO · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [C]
## CONCEPT FRAMEWORK
	**Primary Concept**: Biomagnification
	**Related Topics**: Bioaccumulation, Trophic Levels, Environmental Pollution
	**Prerequisites**: Understanding of food chains/webs and the concept of trophic levels
## SOLUTION PATHWAY
**Given Information**:
	* Non-biodegradable substances accumulate in organisms.
	* Concentration increases as you move up the food chain.
**Method & Steps**:
	1.	Identify the key process: The question describes a process where substances become more concentrated at higher levels of a food chain.
		Reasoning: This directly relates to how toxins accumulate in ecosystems.
	2.	Review the definitions of the given options.
		Key Point: Understanding the difference between bioaccumulation and biomagnification is crucial.
	3.	Select the option that accurately describes the described process.
		Result: Biomagnification is the correct term.
 ## OPTION ANALYSIS
[A] :x: Eutrophication is the process of nutrient enrichment in a water body, leading to excessive plant growth. It doesn't directly relate to the accumulation of toxins at different levels.
[B] :x: Bioaccumulation is the accumulation of substances within an organism over time. It doesn't explicitly describe the increase in concentration across trophic levels.
[C] ✓: Biomagnification is the correct term for the process of increasing concentration of substances (especially toxins) at successive trophic levels of a food chain.
[D] :x: Biodegradation is the process by which substances are broken down by living organisms. It's the opposite of accumulation.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing bioaccumulation and biomagnification. Bioaccumulation is within one organism, while biomagnification is across trophic levels.
		2.[Error 2]: Assuming all accumulation processes are the same. The question specifies the increase in concentration at successively higher levels, which is biomagnification.
	**Quick Tips**:
		1.[Helpful shortcut]: Remember 'magnify' means to increase, and biomagnification is about the increase in concentration up the food chain.
		2.[Memory aid]: 'Bioaccumulation' is within one, 'Biomagnification' is across many levels.
